Synovial Osteochondromatosis of the Cervical Spine: A Case Report1

Abstract

Synovial osteochondromatosis is a rare, benign condition characterized by formation of cartilaginous nodules within the synovium. It rarely occurs at cervical spine, and only six cases have been previously reported in the English literature. We describe another case of synovial osteochondromatosis in the cervical spine in a 77-year-old man who presented with compressive myelopathy. Here we briefly review the literature and discuss the differential diagnosis based on CT and MR findings.
